INTRODUCTION
Suitable for fabric ,children`s sleepwear and protective clothes ,used to test damaged length,afterglow time,and afterflame time of vertically oriented specimens.
Used for testing the continued burning time, smouldering time and damage length of protective clothing and all kinds of fabrics in the vertical direction.
Equipped with sealed stainless steel combustion chamber, observation window and standard burner, can timely detect the flame vertical spread rate.
Different test standards require different sample clips and metal accessories, which should be indicated.
